Abstract: A method for detecting thermal runaway of a cell includes: positioning a battery pack having multiple cells in an automobile vehicle; measuring a cell voltage of the multiple cells at a predetermined sample rate; and identifying if the cell voltage decreases and modulates coincident with a cell surface temperature increase indicating initiation of a cell short.

Abstract: Methods and apparatus are provided for active vehicle cabin occupant detection system. The method includes predicting the presence of a vehicle occupant during operation of a vehicle in response to a door sensor indicative of a door opening, a carbon dioxide level and a pressure sensor in a passenger seat indicative of the vehicle occupant in the passenger seat, detecting the presence of the vehicle occupant using a vehicle cabin motion detector in response to the vehicle being shutdown, confirming the presence of the vehicle occupant using an infrared camera to detect a thermal signature of the vehicle occupant in response to the predicted presence of the vehicle occupant, and transmitting an alert via a wireless transmitter indicative of the presence of the vehicle occupant.

Abstract: An environment interactive system includes: a first camera capturing first images of an area external to the vehicle; a second camera capturing second images of an area interior to the vehicle; a telematics control module determining a geographical location of the vehicle; a viewing device displaying items adjacent to, on or in front of detected objects and in a FOV of an occupant. The items correspond to the detected objects; and an infotainment module. The infotainment module: detects the objects based on the first images and the location of the vehicle; based on the second images, tracks at least one of a location of an eye of the occupant or a location of a body part of the occupant other than the eye; and based on the location of the eye and the location of the body part, displays the items via the viewing device in the FOV.
